Physical Symptoms of Anxiety
Learn about common physical sensations associated with anxiety, why they can happen, and when symptoms should be checked by a healthcare professional.
Quick answer
Anxiety can affect the body as well as the mind. Possible sensations include a faster heartbeat, sweating, shaking, dizziness, breathlessness, headaches, stomach symptoms and muscle tension. Because these symptoms can also have other causes, new, severe or concerning symptoms should be medically assessed.
Physical sensations can be one of the most frightening parts of anxiety, especially when you do not immediately connect them with stress or worry.
The body’s threat response can create noticeable changes quickly. Understanding that connection can reduce confusion, but it is important not to use anxiety as a blanket explanation for every symptom.
Common physical sensations linked with anxiety
The NHS lists a wide range of physical symptoms that can accompany anxiety, fear and panic. Different people experience different combinations.
- A faster, irregular or more noticeable heartbeat
- Feeling light-headed or dizzy
- Sweating or feeling hot
- Shaking or trembling
- Breathlessness or changes in breathing
- Headaches
- Muscle tension
- Chest discomfort
- Loss of appetite or stomach upset
- Nausea, cramps, bloating, constipation or diarrhoea
Why anxiety affects the body
When the brain detects possible danger, the body can release stress hormones such as adrenaline and cortisol. These changes are designed to prepare you to respond.
A faster heartbeat, changes in breathing and increased muscle tension can therefore happen even when the threat is emotional, uncertain or imagined rather than a physical danger in front of you.
The sensation–worry cycle
You may notice a sensation, become worried about what it means, and then experience more anxiety. The increased anxiety can intensify the original sensation, which makes it feel even more significant.
Recognising the cycle can help you avoid treating every change in your body as proof of catastrophe.
What can help in the moment
1. Orient to the present
Notice where you are and what is actually happening around you.
2. Relax unnecessary tension
Unclench your jaw, drop your shoulders and loosen your hands if they are tense.
3. Let breathing be comfortable
Avoid forcing very large breaths. Aim for steady, comfortable breathing.
4. Avoid repeated body checking
Constantly checking a sensation can keep attention locked onto it and make it feel more prominent.
When should physical symptoms be checked?
Do not assume a new or worrying physical symptom is “just anxiety.” Seek medical advice if you are concerned, especially if symptoms are severe, new, persistent or unusual for you.
If you think you may be having a medical emergency, seek urgent medical help.
